Chuño—freeze-dried potatoes are not just for astronauts

In the early 13th century, the Incan empire succeeded in expanding its rule along the entire span of the Andes Mountains in South America. At its height, the empire controlled portions of what are now five countries, including Ecuador, Bolivia, Peru, and Chile.

The process allowed the food to be stored for long periods of time and carried for long distances over the rugged terrain of the Andes.
